The Canadian Commission on Building and Fire Codes invites interested parties to take part in the fall 2018 public review of proposed changes to the 2015 editions of Codes Canada publications. The review will run from November 7, 2018 to January 4, 2019. Visit the Codes Canada webpage for explanations about the proposed changes and for instructions on how to submit comments.
The purpose of the public review is to provide Code users and stakeholders with a detailed look at changes being considered and to seek comments as to whether changes should be approved, altered, or rejected. Following the review, each comment received will be considered and recommendations on the proposed changes will be made by the responsible standing committee. The final changes are subject to approval by the Canadian Commission on Building and Fire Codes and will be published by the National Research Council in the 2020 editions of the Codes Canada publications.
Below is a summary of the most significant proposed changes:
As the Canadian population gets older, the demand to accommodate residents who require continuous care is increasing. To address this growing trend, a new home-type care occupancy is proposed in the National Building Code and the National Fire Code. This new occupancy allows more affordable accommodations for residents who require in home-type care without compromising fire and life safety.
The 2018 public review introduces a number of proposed changes that address the growth and transmission of Legionella bacteria in buildings. Legionnaires’ disease is a potentially fatal respiratory illness that is caused by exposure to Legionella bacteria. These changes are intended to minimize adverse health effects caused by Legionella and other bacteria.
In some cases, the current Code allows windows to be openable without restriction and may not sufficiently prevent children from falling out. To increase the safety of openable windows, a proposed change adds flexibility to the design of these windows. This simple solution adds protection to windows in houses and aims to ensure safety without compromising other design considerations.
Part 5 of the National Building Code provides general guidance on the intended performance of air barrier systems, but does not provide specific performance criteria, except for individual materials forming part of a larger air barrier system. Changes proposed to Part 5 address air leakage by shifting the focus from materials to the performance of air barrier assemblies. This proposed improvement is intended to provide clarification of known approaches and better reflects current practice.
